    摘要： The use of a fabric sheath (2), or other article, on a conduit (1), for example a pipe or flexible hose, to provide abrasion resistance or other forms of protection, for example impact protection or cut-through protection, thereto; and fabric sheaths suitable for such use. A preferred form of circumferentially-heat-shrinkable sheath of woven fabric, capable of use on a conduit, for example to provide impact cushioning and/or abrasion resistance, provides a substantially unobscured outer fabric surface and comprises hoop filaments extending substantially circumferentially around the sheath, at least some of which hoop filaments are heat-shrinkable, and length filaments extending substantially along the sheath, wherein the length filaments are selected either (A) to be sufficiently flexible, at least at temperatures to which they are subjected during heat-shrinking of the sheath in use, for the heat shrinkage of the hoop filaments to crimp the length filaments to an extent (a) producing at least 1%, preferably at least 2%, more preferably at least 5%, longitudinal shrinkage of the sheath in addition to any longitudinal heat shrinkage thereof and/or (b) causing portions of the length filaments either (i) to project outwardly from the shrunken fabric sheath to a maximum distance in excess of the maximum projection distance of the thus-shrunken hoop filaments, or (ii) to increase such excess projection distance if already existing before the heat shrinkage; or (B) to be sufficiently stiff to limit the longitudinal shrinkage due to crimping of the length filaments to less than 10%, preferably less than 5%, more preferably less than 2%, especially less than 1% or substantially zero.

    摘要： A fabric cover (9, FIG. 2a), which is shrinkable at least in part, for encapsulating at least part of an expandable object such as an automotive airbag (1), the fabric cover being provided with a predetermined region of weakness (13), preferably a catch thread holding the edges of a woven fabric together to form a tubular or flat cover, which region of weakness will rupture when the said object expands by greater than a predetermined amount, e.g. in an automobile accident. The region of weakness (13) and preferably fabric regions (11) immediately adjacent thereto may be of a contrasting color to facilitate alignment of the region of weakness in the direction of expansion of the expandable object.
